UHF RFID

How It Works

UHF RFID is a wireless identification technology operating in the 860–960 MHz frequency range. It enables fast and accurate identification of tagged items, with read ranges of up to 15–20 meters and the ability to process hundreds of tags per second. Using passive, battery-free tags, UHF RFID offers a cost-effective and maintenance-free solution for applications such as warehousing, asset tracking, retail, logistics, and manufacturing.

Choosing the right RFID antenna depends on the reading range, coverage area, tag orientation, installation position, and application environment. Choose the antenna gain and beam pattern based on the required coverage, and consider circular or linear polarization according to tag orientation and movement. For multi-antenna systems, the antenna layout should also be matched to the reader and the required reading zones.

Metal, liquids, and other materials can affect RFID signal performance, so different tag designs are available for different applications. Choose the right tag based on the material of the item, required read range, mounting method, and environmental conditions. For outdoor or harsh environments, consider the tag’s protection rating, durability, and temperature resistance to ensure reliable long-term performance.
